Mother talzin or asajj - whose the better leader

I use Talzin more than Asajj because I think she’s a bit better, but they are both good leaders.

Talzin seems more frequent in my arena shard. They have different uses in different raids. Asajj can solo the Rancor. Talzin can, with tons of work, solo or partially solo the HAAT. They also both have specific uses in HSith. Asajj strategy is easier than Talzin for that though.

It depends where you're using them.

I find it depends on the scenario, but I prefer MT as lead on Defence for some reason. Don't know why

Asajj seems to be more effective (Raid, TW, GA) but Talzin is really fun, and a good def leader in 3v3.

It depends if you are in attack or defense.
I would say Talzin to set a team for defense (last fight of the day in Arena, or set a defense in TW/GA)
And Asajj to attack.

In arena, I find Talzin to be much harder to fight against. The constant revive/assist on top of the plague really does some big damage.
